ABA Cardiac Anesth study guide
ABA Cardiac Anesth · Work through your exam, one topic at a time.
The Adult Cardiac Anesthesiology Exam is one of the subspecialty examinations listed by the American Board of Anesthesiology (ABA), appearing alongside the board's other subspecialty exams. Subspecialty certification is intended for anesthesiologists who already hold primary certification in anesthesiology and who want formal recognition of advanced expertise in the perioperative care of patients undergoing cardiac surgery and related procedures. The ABA Cardiac Anesth study guide has 7 sections and about 2,173 words.
01Fundamentals of Cardiac Anesthesia: Anatomy, Physiology, and Pharmacology
The cardiac anesthesiologist manipulates three levers-preload, afterload, and contractility-but must predict how drugs and ventilation change all three at once. Understand the pressure-volume loop: end-diastolic volume sets stroke volume via Frank-Starling; the end-systolic pressure-volume relationship indexes contractility; stroke work is loop area.

For cardiac surgery, use procedure-specific tools such as STS and EuroSCORE II, not the Revised Cardiac Risk Index, which was validated for noncardiac surgery. For noncardiac surgery in cardiac patients, define urgency, active cardiac conditions, functional capacity, and perioperative risk.

Standard monitoring includes ECG, pulse oximetry, capnography, temperature, and noninvasive blood pressure; cardiac surgery usually adds invasive arterial pressure and central venous access. Arterial lines provide beat-to-beat pressure and blood sampling, but accuracy depends on transducer level, damping, and waveform quality.

Cardiopulmonary bypass replaces gas exchange and circulation with a venous reservoir, pump, oxygenator, heat exchanger, and arterial filter. Maintain adequate flow indexed to body surface area, mean arterial pressure, and oxygen delivery; flow and pressure are not interchangeable.

Initial ICU care focuses on airway and ventilation, hemodynamics, bleeding, pain, temperature, and neurologic status. Fast-track extubation is feasible in selected patients, but do not extubate a patient with excessive bleeding, instability, or encephalopathy.

Congenital heart disease questions hinge on shunts and parallel circulations. A left-to-right shunt raises pulmonary blood flow; a right-to-left shunt causes cyanosis and risk of paradoxical embolism.

Patient safety in cardiac anesthesia depends on systems, not heroics. Use structured checklists, time-outs, medication labeling, and standardized handoffs.
